[NTG-context] Math align with \startcases
Hi everyone,
This question is primarily intended for Aditya… but I guess other
fellows on the list can also help me solve the following alignment
problem:
Is it possible to have an alignment like the rsult of the following
with \startcases...\stopcases?
\starttext
\startformula
\startmatrix[align={right,left,right},distance=3pt,left={\left\{},
right={\right.}]
\NC -\Delta u + g(u) \NC{} = f \NC \quad\mbox{in } \Omega\NR
\NC \displaystyle {\partial u \over \partial {\bf n} } \NC{} =
h(u) \NC \quad\mbox{on } \partial\Omega \NR
\stopmatrix
\stopformula
\stoptext
Actually I used to have such alignments with the following structure
(in good old plain TeX...):
\starttext
\startformula
\cases{
\eqalign{
-\Delta u + g(u) = f \cr
\displaystyle {\partial u \over \partial {\bf n} } = h(u) \cr
} \quad \eqalign{
\hbox{in } \Omega \cr
\vphantom{{\partial u \over \partial {\bf n} }} \hbox{on } \partial
\Omega \cr
}
}
\stopformula
\stoptext
(which gives approximately the same result as the first example above,
but clearly the math-alignment structure set up by Aditya and Hans is
much more elegant. (Although I prefer the vertical distance between
the lines obtained with my plain TeX structure: by the way is it
possible to fine tune such things in ConTeXt).
So my question is: whether one can use \startcases ...\stopcases
instead of \startmatrix ... \stopmatrix in order to obtain the result
of the plain TeX example?
Thanks in advance: OK

No, but there is not much difference between cases and matrix. Consider:
\definemathmatrix[alignedcase]
[align={right,left,right},distance=3pt,left={\left\{},
right={\right.},style=\displaystyle]
\starttext
\startformula
\startalignedcase
\NC -\Delta u + g(u) \NC{} = f \NC \quad\mbox{in } \Omega\NR
\NC {\partial u \over \partial {\bf n} } \NC{} = h(u) \NC \quad\mbox{on
} \partial\Omega \NR
\stopalignedcase
\stopformula

Thanks Aditya: actually an alternative definition in order to get what
I mentioned in my question is the following:
\starttext
\definemathmatrix[alignedcase]
[align={right,left,left}, % instead of
align={right,left,right}
distance=3pt,
left={\left\{},
right={\right.},
style=\displaystyle]
\startformula
\startalignedcase
\NC -\Delta u + g(u) \NC{} = f \NC \quad\mbox{in } \Omega\NR
\NC {\partial u \over \partial {\bf n} } \NC{} = h(u) \NC \quad
\mbox{on } \partial\Omega \NR
\stopalignedcase
\stopformula
\stoptext
Should I add this to the wiki?
Many thanks: OK
